## System Requirements
- Linux:
- [Mono]( (`dotnet` might work but is untested)
- Windows:
- Visual Studio (the free version is fine - it's just the developer command prompt you need)
- All operating systems:
- [Git]( (`sudo apt install git` on apt-based systems)
- For printing:
- [Inkscape](
- [ImageMagick]( (`sudo apt install imagemagick` on apt-based systems)
- [pdfposter]( (`sudo apt install pdfposter` on apt-based systems)
## Getting Started
This program is written in C♯. To get started, first clone this repository and compile it:
git clone
cd MusicBoxConverter

This should work regardless of whether you're on Linux or Windows.
If you're on Windows, you'll either need to use a _Visual Studio Developer Command Prompt_ or open the solution file in _Visual Studio_ itself and hit the build button.

Once the build is complete, the binary (and associated libraries) can be found in `MusicBoxConverter/bin/Debug` (or `MusicBoxConverter/bin/Release` if you did a release build).

If you're having trouble building it, please [get in touch]( and I'll send you a build (when [this bug is fixed](, I'll be able to create a release and upload the binaries there)
## Usage
1. Export the MuseScore file to a MIDI file
2. Run the MIDI file through this program.
3. Open the resulting SVG in Inkscape
4. Print the SVG to PDF (or `inkscape --export-pdf output.pdf input.svg`)
5. Open the resulting PDF in LibreOffice Draw
6. Print to your actual printer - tiling over multiple pages if required.

This somewhat convoluted process prevents anyone from automatically rescaling it along the way, and thus misaligning the green lines in the SVG file generated by the program.
If the above doesn't work, it's probably LibreOffice Draw scaling it even though you've told it not to. In that case, try this:
# Convert MIDI -> SVG
./MusicBoxConverter.exe --input song.midi --output score.svg

# Convert SVG → PNG
inkscape -o score.png score.svg
# Convert the PNG to PDF, rotating by 90 degrees (for portrait printing)
convert score.png -rotate 90 score.pdf
# Split the PDF up into multiple pages for the printer
# -s1 Don't scale the output
# -m Sets the output paper size. Defaults to A4 (21x29.7cm) if unspecified, but may need to reduce by a cm or 2 on each side (as below) if things get cut off.
pdfposter -s1 -m 20x27.7cm score.pdf print.pdf
....if that cuts things off at the edges, try doing it like this:
convert score.svg score.pdf
pdfposter -s1 score.pdf print.pdf

Contributions are very welcome - both bug reports and code contributions! Bug reports can be made to my email address (available on my website <>). Code contributions can be sent as a patch via email. Do this to generate a patch file you can attach to an email:
git format-patch --stdout origin > patch_file.patch
This generates a patch file for all unpushed commits. To specify a specific commit range, do this:
git format-patch --stdout FIRST_COMMIT..LAST_COMMIT > patch_file.patch
Please mention in at least 1 commit message that you release your all your work under the MPL-2.0 (see below), as otherwise I will be unable to accept it (work you produce is as far as I know automatically copyright, so unless you release it under a licence no matter how awesome it is I'm not allowed to use it).
If there's significant interest in this, I can move it to [my GitHub account]( to make collaboration easier.
If you're feeling that way inclined I have a [Liberapay profile]( if you'd like to donate to say an extra thank you :-)
